Wireless network card always stop work after running the application

Hi Shilv,

Is it a custom board? Could you provide more detailed log (using logcat command) from appearing the issue.

What is the bitrate of the encoded h264 stream?

I use ./encode > log.txt to store the application print message

following is the message printed by kernel (out of the log.txt):

I think the bitrate of the encoded h264 stream is not the reason, because I have used the same send code and same card to send file on very high bitrate,the card works well.

It is a board desinged by my lab members.

Sometimes It will reprot the kernel panic. If I disabled the encode part in the code, just send some fixed data in a buffer,the card won't reprot the error.

So I think it has relationship with the encoder. Maybe I set error parameter to the encoder.

the VIDENC1_Params and VIDENC1_DynamicParams is as follow:

{                                   /* VIDENC1_Params */
            sizeof(VIDENC1_Params),          /* size */
            XDM_DEFAULT,                            /* encodingPreset */
            IVIDEO_STORAGE,                      /* rateControlPreset */
            0,                                                      /* maxHeight (set at runtime) */  // 480
            VGA_WIDTH,                                 /* maxWidth */                  // 640
            30000,                                            /* maxFrameRate */
            4096000,                                        /* maxBitRate */
            XDM_BYTE,                                   /* dataEndianness */
            1,                                                     /* maxInterFrameInterval */
            XDM_YUV_422ILE,                      /* inputChromaFormat */ 
            IVIDEO_PROGRESSIVE,            /* inputContentType */
            XDM_CHROMA_NA                     /* reconChromaFormat */
        },
        {                                                   /* VIDENC1_DynamicParams */
            sizeof(IVIDENC1_DynamicParams), /* size */
            0,                                            /* inputHeight (set at runtime) */    // 480
             VGA_WIDTH,                      /* inputWidth */                    //640
            30000,                                 /* refFrameRate */
            30000,                                 /* targetFrameRate */
            4000000,                             /* targetBitRate */
            30,                                         /* intraFrameInterval */ 
            XDM_ENCODE_AU,          /* generateHeader */
            0,                                           /* captureWidth */
            IVIDEO_NA_FRAME,          /* forceFrame */    
           1,                                             /* interFrameInterval */
           0                                               /* mbDataFlag */

}

The red parameter is which I am wondering:

 1.rateControlPreset ,this version encoder doesn't support IVIDEO_LOW_DELAY, which means CBR,I have to set IVIDEO_STORAGE(VBR),is it OK?

2. The camera output framerate is 30fps,but I used while loop in my code, the input of encoder cannot reach 30fps. Can the value of framerate be 30fps?

3.How to determine the value of bitrate?

Need your help.

The problem of kernel hanging have been sloved by changing the kernel verion.

But the problem of wireless USB NIC stopping working have not been sloved.

I removed the capturing and sending part , and the application only has the H264 encoder, after running the encode application for 5~10min, " the network is unreachable"

It shows that the running of encoder has an impact on USB wireless NIC.

Who can help me ?
